Selecting design points on parameter functions having first sum of constraint set and second sum of optimizing set to improve second sum within design constraints

摘要

In one embodiment of the invention, parameter functions for a plurality of circuits in a subsystem are created. The subsystem has design constraints. Each one of the parameter functions corresponds to each one of the circuits. The parameter functions represent a relationship among design parameters of the subsystem. The design parameters include constraint and optimizing sets. Initial design points are selected on the parameter functions having a first sum of the constraint set and a second sum of the optimizing set such that the first sum satisfies the design constraints. New design points are selected on the parameter functions such that the second sum is improved within the design constraints.
